Description

Electronically controlled driving device for torsion lace jacquard {Torchon lace Jacquard loom}

The present invention mainly relates to a jacquard loom for weaving a torchon lace. Particularly, a torsion which is controlled by a computer signal without rubbing as a mechanical control means for controlling the position of bobbin according to the designed pattern. An electronically controlled driving device for a lace jacquard machine.

A torsion lace refers to a lace made of simple linen or cotton with thick linen or cotton yarn, and is mainly used for the decoration of the neck and sleeves of women's cotton. Conventional jacquard (originally Jakar) looms for use in weaving such fabrics are machines that have not yet been classified into fabric organization.

The method and structure of the conventional jacquard loom and the operation sequence will be described with reference to FIGS. 1 and 2. The tissue is first analyzed to indicate on the design paper where to drill and where not to fit the jacquard needles (1,1 ', ...). The rub 2 is prepared, aligned with the design paper, and a hole is drilled in the rub 2 in that order. The punched rub 2 is woven in order.

For the installation of the rub 2, first, the left and right sides of the medal cap and the intermetallic mounting bolts (not shown) are removed, and the holes 3a through which the ends of the jacquard needles 1, 1 ', ... can be inserted are patterned. The rubbing 2 is passed through the jacquard cylinder 3, which is constantly formed, and is installed in a plurality of rollers 4 in a caterpillar manner as shown in FIG. In order to match the hole 3a of the jacquard cylinder 3 with the hole drilled in the rub 2, the left and right positions and the rotational state are checked and fixed.

When operating, the odd-numbered row of operating levers 5 and the even-numbered row of operating levers 6 alternately move up and down by a series of cam devices (not shown). Each of the operating levers 5 and 6 is provided so as to hook the hooks 7 and 7 'in the movement direction thereof. The hooks 7 and 7 'are constrained to reciprocate a certain distance in the holes 8 and 8' of the hook guide placement plate 9 in which a plurality of holes 8 and 8 'are arranged in two rows.

The reciprocating motion of the predetermined distance is installed between the fixing piece 10 and the fixing guide piece 11 and the middle is made by the jacquard needle 1 fixed in the middle of the hooks 7 and 7 '. For example, when one jacquard needle 1 advances to the right in FIG. 1, the end of the hook 7 is caught by the corner of the operating lever 6, and when the jacquard needle 1 is reversed, the end of the hook 7 is operated by the lever. Depart from the corner of (6).

Advancement of the jacquard needles 1, 1 'means that the hole of the rubbish 2 is opened according to an arbitrary pattern pattern, and the hole 3a of the jacquard cylinder 3 which rotates in one direction while the rubbish 2 is spread. When they coincide with each other, it means that the end of the jacquard needle (1, 1 ') enters into the coincident hole.

On the other hand, the retraction of the jacquard needles 1, 1 ′ means that the jacquard needles 1, 1 ′ do not enter the hole 3a of the jacquard cylinder 3 because the rubbing 2 is not drilled. do. Thus, when the jacquard needles (1,1 ') move forward, the hooks (7,7') are pulled upward by the operating lever (5,6) which periodically moves up and down, and when the jacquard needles (1,1 ') move backward, the hooks (7,7 ') is not pulled.

For example, when the hook 7 is pulled, the tension wires 13 and 14 on both sides of the connecting lever 12 are pulled in the direction of the arrow. Then, as the lever 16 installed below the lower plate 15 rotates counterclockwise, the lifting shaft 17 rises about the hinge 18. At the same time, the poker 19 is raised and the clutch 20 held between the poker 19 is also raised at the same time to engage the lower portion of the rotor 22 installed on the upper plate 21, thereby driving the rotor by the drive gear 23. (22) rotates.

When the rotor 22 rotates with the adjacent rotor 22 ', the left and right positions of bobbins (not shown) installed in both rows of the rotor 22 and the rotor 22' are changed and the knife (not shown) operates at the same time. By forming the secondary tissue and alternating the even and odd numbers, the continuous tissue is formed to obtain the product of the desired design.

However, according to the conventional jacquard loom, the number of rubs may be several thousand depending on the size of the design, and also it is necessary to have a separate driving device for guiding such rubs continuously. The proportion is large, and the area occupied by them is also large, which takes up a lot of installation space.

In addition, it is necessary to precisely drill holes on a single sheet of paper, and even if one hole is incorrectly made, the overall pattern does not constitute a desired design, and when mechanical deterioration or assembly deviation prevents them from joining in the correct position. It also had a serious problem of producing large quantities of unpredictable defective products rather than the intended design.

This problem occurs without any exception in the process of arranging perforated rubble, and if any one of thousands of rubble is changed due to a worker's mistake, it becomes unpredictable.

Like this, it is very difficult to drill through the dots designed on one piece of paper without any problems and weave the number of sheets without changing the order of the pieces. As described in the above prior art, the method of installing the paper is also very precise and accurate. It requires a high level of skill and labor. In addition, the same process every time the design changes, the labor waste and the economic loss are inevitable.

The present invention aims to improve work efficiency and increase operation reliability by using a rubbed device as an electronic control means for controlling the left and right positions of the bobbin according to the designed contents.

Another object of the present invention is to remove all complicated and inexpensive mechanical elements and replace them with electronic control means controlled according to the input value of the computer to create high value through miniaturization and high-end of the device.

In order to achieve the above object, if the hook is selectively caught by one of two actuating levers alternately reciprocated by the cam device, the clutch is engaged by the tension of the actuating lever and the rotor rotates by the drive gear. In changing the left and right positions as one unit movement, a rod is connected to the middle of the unit moving hook, and an end of the rod is provided with a solenoid for operating the rod so that the hook can be caught by the operating lever. This solenoid is operated according to the output signal of the computer which outputs according to the designed input value.

In the above manner of transmitting the kinetic force of the hook to the poker can take two ways. One of the methods is the same as the conventional method. Connect one end of the hook to the interlocking lever, and connect the interlocking lever and the lever for moving the lifting shaft of one side of the poker up and down with a tension wire, but interposing the lever in the middle of the tension wire It is.

Alternatively, in a conventional connection type in which a tension wire is connected to a lever interlocking with the lifting shaft to operate the lifting shaft of one side of the poker up and down, one end of the hook is directly connected to one end of the tension wire connected to the lever. will be.

According to the present invention configured as described above, when the solenoid is operated by the output signal of the computer, the rod pushes the hook and the hook is caught at the end of the corresponding operating lever. In this state, when the operation lever pulls the hook, the lifting shaft is raised, the clutch is engaged with the rotor shaft, and the driving gear rotates the rotor, thereby changing the left and right positions of the bobbin. Therefore, it is possible to receive a reliable operation without requiring a separate mechanical drive for supplying rub.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 3 shows an embodiment of the present invention. The two operation levers 31 and 32 alternately move up and down as shown by an arrow. The vertical movement of the operation levers 31 and 32 is performed by a series of cam devices 33. Each of the operation levers 31 and 32 is provided so that a plurality of hooks 34 and 34 'can be caught or removed at regular intervals.

The ends of the hooks 34 and 34 'are bent into an L-shape so that one end of the L-shape is caught by the longitudinal edges of the actuating levers 31 and 32. A plurality of hooks 34, 34 ', ... (only two are shown in the drawing) are fitted to the hook guide placement plate 36 in which the long holes 35, 35', ... are arranged in two rows in succession. . The hooks 34, 34 ', ... are inserted into the first and second rows of the hook guide placement plate 36 one by one (one across each other), and the hooks 34' by the odd long holes 35 'in the first row. In the second row, the hooks 34 are fitted into the even holes 35.

Thus, one of the actuating levers 31 and 32 has hooks 34 'fitted into the long hole 35' of the hook induction placing plate 36, and the other actuating levers 32 have two hooks. Hooks 34 fitted in the long holes 35 of the row are caught. The other ends of the hooks 34 and 34 'are connected to the interlocking levers 37 and 37'. One end of the hooks 34 and 34 'is pivoted about the interlocking levers 37 and 37' within the length of the long holes 35 and 35 'of the hook guide placing plate 36. As shown in FIG. This turning means that one end of the hooks 34, 34 'is caught or pulled out by the actuating levers 31,32.

The pivoting of the hooks 34, 34 ′ is accomplished by rods 38, 38 ′ connected in the middle of the hooks 34, 34 ′. The rods 38 and 38 'are installed to be pulled by the solenoids 40 and 40' attached to the fixing piece 39. In addition, the rods 38 and 38 'are provided with tension springs 41, and when the solenoids 40 and 40' are turned off after being pulled according to the operation of the solenoids 40 and 40 ', the rods 38 and 38' are tensioned. It returns by the spring 41. When the solenoids 40 and 40 'are actuated and the rods 38 and 38' are pulled, the hooks 34 and 34 'pivot about the interlocking levers 37 and 37' so that one end of the hooks 34 and 34 'is rotated. The hooks 34 and 34 'rise as the operating levers 31 and 32 are raised by the operating levers 31 and 32. As shown in FIG.

On the other hand, when the solenoids 40 and 40 'are off, the hooks 34 and 34' are pulled out of the actuating levers 31 and 32. Stay as it is. It is the computer 42 that actuates the solenoids 40, 40 ′. The computer 42 inputs a coordinate point according to a design pattern for weaving a lace and outputs it to the solenoids 40 and 40 'when the coordinate point is reached.

In the present invention, one hook (34 or 34 ') to one rotor (43 or 43') is configured as a unit element. In practice, the jacquard loom has these unit elements arranged continuously in a column. Thus, when describing on the basis of an element involving one unit motion, the hook 34, which can be caught by an even number of operating levers 32, is connected to the interlocking lever 37, and the interlocking lever 37 is also tensioned. It is connected to the connecting lever 45 by the wire 44. The connecting lever 45 is connected to the lever 47 connected to the bracket 46 by the tension wire 48.

The bracket 46 is fixed to the lower part of the lower plate 49, and the lifting shaft 50 is connected to the hinge 51 at one end of the L-shape. The lifting shaft 50 is fixed to the poker 53 provided below the upper plate 52 on the lower plate 49. The clutch 54 is engaged between the pokers 53, and the clutch 54 is engaged with the shaft of the rotor 43 when the poker 53 rises as the lifting shaft 50 rises.

A drive gear 55 is provided below the clutch 54 so that when the clutch 54 is engaged with the rotor 43, the driving force is transmitted to the rotor 43 to rotate the rotor 43 in one direction. The return shaft 56 is installed on the lifting shaft 50 so that the operating force of the lever 47 is not transmitted to the lifting shaft 50 and lowers together with the poker 53. The clutch 54 also rotates with the rotor 43. As a result, the rotational force of the drive gear 55 is not transmitted to the rotor 43. A bobbin (not shown) is installed between one rotor 43 and a rotor 43 'adjacent thereto so that the bobbin rotates in one direction according to the rotation of the rotors 43 and 43' to form a thread.

An operation according to such an embodiment will be briefly described. First, an input value corresponding to the designed pattern is input to the computer 42. When the cam device 33 is operated, the odd-numbered row of operating levers 31 and even-numbered row of operating levers 32 alternately move up and down. At this time, when the solenoid 40 is operated in accordance with the output signal of the computer 42, the rod 38 is advanced to the right. Then, one end of the hook 34 is pivoted within the range (length) of the long hole 35 of the hook guide placing plate 36 with the interlocking lever 37 as an axis to be caught by the operating lever 32. The next operation lever 32 is raised and pulls the hook 34 upward.

When the hook 34 is pulled, the tension wires 44 and 48 are pulled. Accordingly, as the lifting shaft 50 is raised, the poker 53 is raised to engage the clutch 54 with the shaft of the rotor 43 so that the driving force of the driving gear 55 is transmitted to the rotor 43. When the rotor 43 rotates with the adjacent rotor 43 ', the left and right positions of bobbins (not shown) installed in both rows of the rotor 43 and the rotor 43' are changed and the knife (not shown) operates at the same time. By forming the secondary tissue and alternating the even and odd numbers, the continuous tissue is formed to obtain the product of the desired design.

Figure 4 shows another embodiment of the present invention. In this case, it is configured in the same manner as in the above embodiment, but the other end of the hook 34 is directly connected to the tension wire 48 connected to the lever 47. Thus, when the hook 34 is pulled to the right by the actuating lever 32, the tension wire 48 rotates the lever 47 to raise the lifting shaft 50. The rest of the configuration and operation sequence are one embodiment. Since it is the same as the example, the description is omitted.

5A and 5B are examples in which the solenoids 40, 40 '(unified to 40 below) pull the hooks 34, 34': unified to 34 below. Figure 5a is a case applied to Figure 4 showing another embodiment of the present invention, Figure 5b is applied in Figure 3 showing an embodiment of the present invention. That is, FIG. 5A illustrates that the rod 38 connected to the middle of the hook 34 is upwardly moved by the solenoid 40 by placing one end of the hook 34 below the operating levers 32 and 31 (unified to 32). It was installed to pull. In this case, one end of the hook 34 is caught by the end of the operating lever 32 by the operation of the solenoid 40. When the solenoid 40 does not operate, one end of the hook 34 is applied to the weight of the hook 34. By returning downward by the operation lever 32 is released.

On the other hand, FIG. 5B shows that one end of the hook 34 is positioned above the operating lever 32, and the rod 38 connected to the middle of the hook 34 is pulled downward by the solenoid 40. The upward return of 34 is installed by spring force. The means for upward return of the hook 34 is preferably a tension spring 41, but other elastic materials such as spantex may be used. Therefore, when the solenoid 40 is operated, one end of the hook 34 is caught at the end of the operating lever 32, and when the solenoid 40 is not operated, one end of the hook 34 is a spring force such as the tension spring 41. It returns from the operating lever 32 while returning upward.

The present invention configured as described above eliminates the trouble of penetrating through the rubbing and the error caused by the device by rotating the rotor by the operation of the solenoid according to the output of the computer, without using the conventional rubbing device, thereby reducing work efficiency and precision. And ease of operation are greatly improved. In addition, by reducing the area occupied by the use of a conventional rub, it is possible to reduce the size of the device, as well as to significantly reduce the cost, such as manufacturing cost is very economical.
